I guess, not that it really helps though. It just makes it even more implausible that the Excelsior would be in the exact path of a shockwave that couldn't have been more than a few miles high which originated from lightyears away. All the better is the fact that it snuck right up on them. It'd be like driving a car into a tree... in Antarctica.
I had a science teacher who said you could point in any direction outside our solar system and your odds of ever hitting anything were something like one in 10 to the 33rd power (10^33).
It's incredible all of the things our crews have "randomly" ran into over the years. Best to just not think about it.
